Cholesteatoma is a destructive and expanding growth that consist of skin cells in the wrong places of the middle ear and mastoid. If left untreated, it can eat into the three small bones that are located in the middle ear. Cholesteatoma can also affect and erode the thin bone structure that isolates the top of the ear from the brain, as well as lay the covering of the brain open to infections. Common symptoms include: hearing loss, discharge from the ear with a strong odor, bleeding from the ear, dizziness, vertigo, balance disruption, ear ache, headaches, and tinnitus.

Types of Cholesteatoma

  • Acquired cholesteatoma is the most common type. It can be caused by a tear or retraction of the ear drum. Acquired cholesteatomas usually arise from the pars flaccida region of the ear drum in the posterior-superior area of the ear drum.
  • Congential cholesteatoma is less common. They are most often found in the anterior area of the ear drum.

Treatment Options

Congenital cholesteatomas of the middle ear can be removed through the ear canal. The majority of cholesteatomas require that an incision be made behind the ear to expose the affected area adequately. These masses are not cancerous but must be removed to prevent the ear from being severely damaged.
